Trunk comparison: Mercedes Benz GLC vs VW Passat Wagon

Key Differences

The VW Passat Wagon offers a significantly longer loading length: +10.2 in (≈15%) with the seats folded down and +7.9 in (≈22%) with the first row upright compared to the Mercedes GLC.

The depth of the trunk (loading edge to trunk floor) is much more pronounced in the Passat with +3.5 in (≈800%). In contrast, the loading edge in the Mercedes is +2.8 in (≈11%) higher above the road than in the Passat.

Smaller differences: The height of the trunk opening is +1.2 in (≈4%) larger in the Passat, the width at the narrowest point is +3.5 in (≈9%) greater in the GLC, and the width of the trunk opening is +2 in (≈5%) wider in the GLC. These values are under 10% and therefore less decisive.

Impact on Usability

For long or bulky cargo (skis, slats, long boxes, flat furniture), the Passat is clearly advantageous: the longer loading area in both seat configurations plus the greater depth create more usable space and allow longer items without awkward angling.

The lower loading edge of the Passat makes lifting heavy items easier and sliding in boxes or luggage more practical.

The GLC scores better with wide loads: the greater width at the narrowest point and the slightly wider opening make loading wide boxes, strollers, or bulky furniture parts easier, which are more critical in width. However, the higher loading edge requires more lifting effort when loading, especially with heavy items.

Practical recommendation: Those who often transport long or heavy items or regularly need a large cargo volume with a flat floor benefit more from the Passat Wagon.

Those who more frequently load wide, bulky goods and need a wider opening are better served by the GLC — provided the higher loading edge is not an obstacle.
